Study of Uranium in Drinking Water around the Sohna Fault Line in Haryana

Abstract

ABSTRACT Quality of drinking water is associated directly with the health of mass population. Therefore, study on radiation level in groundwater has been taken up around the Sohna fault line, Haryana state, India. Uranium concentration has been measured in drinking water samples collected from sources such as hand pump, tube well from different depths around the Sohna fault line, using LED Fluorimetry Technique. Uranium concentration in study area varies from 0.10 μg/L to 223.16 μg/L with an average value of 22.09 μg/L. The average value of uranium concentration is within the safe limit recommended by World Health Organization (WHO, 2011) and Atomic Energy Regulatory Board. The annual effective dose has also been measured in all the water samples and is found to be below the prescribed dose limit of 100 μSvy–1 recommended by WHO (2011). Risk assessment of uranium in water is also calculated using life time cancer risk, life time average daily dose and hazard quotient. The high uranium concentration observed in certain areas is due to interaction of ground water with the soil formation of this region and the local sub-surface geology of the region.
